Heterogeneous catalysis for the one-pot synthesis of added-value chemicals is a growing area in green chemistry. Among various types of organic transformations that are accessible by this approach, acceptorless dehydrogenative coupling (ADC) reactions have been established as efficient processes that generate various classes of organic compounds via the formation of C–O, C–N, C–S, C–C, and CC bonds. In this review, we summarize recent developments on the one-pot synthesis of organic compounds that are driven by the dehydrogenation of alcohols promoted by supported transition-metal catalysts in the absence of hydrogen acceptors. A major feature of the design of such catalysts is the cooperation between the metal sites and the acid and/or base sites on the metal–oxide supports. Recent examples for the organometallic catalysis of ADC reactions of alcohols are presented and their efficiency is put into contrast with that of related reactions carried out using conventional supported transition-metal catalysts. Finally, aspects pertaining to the mechanism and catalyst design of these new ADC reactions are discussed in the context of directions for future developments in this area.

非均相催化剂上与醇的无受体脱氢偶联反应

一锅法合成增值化学品的非均相催化是绿色化学领域的一个新兴领域。通过这种方法可实现的各种类型的有机转化中，无受体脱氢偶联（ADC）反应已被确定为通过形成C–O，C–N，C–S，C生成各种有机化合物的有效过程。–C和CC键。在这篇综述中，我们总结了在没有氢受体的情况下，一锅合成有机化合物的最新进展，该合成是由负载的过渡金属催化剂促进的醇脱氢驱动的。这种催化剂设计的主要特征是金属位点与金属氧化物载体上的酸和/或碱位点之间的协同作用。提出了用于醇的ADC反应的有机金属催化的最新实例，并将其效率与使用常规负载型过渡金属催化剂进行的相关反应的效率进行了对比。最后，在这些领域的未来发展方向的背景下，讨论了与这些新的ADC反应的机理和催化剂设计有关的方面。
